Joel Galenson 8c72eea5ff Use user policy when checking neverallow rules.
When building userdebug or eng builds, we still want to build the user
policy when checking neverallow rules so that we can catch compile
errors.

Commit c0713e86 split out a helper function but lost one instance of
using user instead of the real variant.  This restores that one and
adds it to the neverallow check.

Bug: 74344625
Test: Added a rule that referred to a type defined only
in userdebug and eng and ensure we throw a compile error when building
userdebug mode.
